Effect of ion‐beam implantation on seed vigor of Roegneria Kamoji Ohwi

摘要：

Roegneria Kamoji Ohwi is a cross‐pollinated, long lived and perennial species in Roegneria, Triticeae tribe of Gramineae, has multi‐florets and multi‐seeds and has resistance against humidity and fusarium head blight.Domestic research was focused mainly on genetic variation in morphology, cytology, isoenzyme, RAPD and SSR(Zhou,2000 ).Ion‐beam, as a new source of mutation, has been characterized by its higher mutation rate and wider mutational spectrum with lower damage for the implanted organism (Yuan et al.2003).In this study, ion beam is implanted in seeds to provide abundant mutated colonies for the genetic improvement of Roegneria K amoj i Ohwi.
